E. Stenostoma Jeffr.— Atlantic off Scilly, 690 f. ("Porcupine")! 

 Shetland-Faeroe Channel, 570 f. ("Triton") ! 



Jeffreys' figure of this shell is an excellent one ; that of Sowerby has 

 the last whorl much too large and angular, and the apex should be 

 truncated instead of pointed. Though a Norwegian species, Sars' 

 figure is altogether unlike, being drawn too much out of scale ; the 

 last whorl should be much longer (about half the length of the shell) 

 and the spire shorter. There is a great difference in these three figures. 



E. ephamilla Wats. (/. Conch., vol. 6, pp. 260-2, i89o).^Besides 

 the six localities I have given in the foregoing reference, I detected 

 some living specimens among the dredgings of the Royal Irish 

 Academy Cruise of 1886, from Berehaven, S.W. Ireland, in 20 faths. ; 

 and also another example in Mr. Jordan's collection among some 

 E. philippii var. gracilis, labelled " Hebrides." This species is not 

 always straight ; two of my specimens are slightly curved, and another 

 has the tip only of the spire curved. 



E. subulata Don. — Liverpool and Morecambe Bays ; Dogger- 

 bank, 30 f., a single specimen. I beUeve these, with the Isle of Man, 

 to be the most northern limits for this species, and that the Orkney 

 and Shetland localities should be ascribed to the next. A short 

 broad form has the same dimensions as E. bilineata, but retains its 

 own characters. The young are slightly angulated at the base. "Of 

 the numerous synonyms, glaber of Da Costa is prior to subiila/a and 

 every other, but the present name has been sanctioned by use."^ It is 

 not quite certain, however, that this is the Eulinia which Da Costa 

 indubitably meant to name glaber. 



E. bilineata Alder. — Not so local as the last species. It varies 

 greatly in size and relative proportions, but the adult stage may always 

 be known by the last whorl being disproportionally swollen, and the 

 base of the aperture open, rounded, and thickened. Immature speci- 

 mens are more or less angulated and pointed at the base. It is occa- 

 sionally bent at the tip, and one from Scilly is curved. Specimens 

 from Thurso and the Orkneys are remarkably slender, more so than 

 E. subulata. From the latter species, this differs in being only half 

 the size, with a broader base, the whorls are not so compressed, the 

 suture is deeper, and the mouth projects beyond the profile lines of 

 of the spire, whereas in E. subulata the outer lip is continuous in out- 

 line with the spire, and the base is lengthened out. In fresh specimens 

 the difference in the coloured bands will always serve to distinguish 

 the two, or when the apex is perfect a sure guide is indicated in the 

 first three whorls, which are convex instead of compressed. The 

 largest come from Guernsey and Torbay, and attain four lines by one.
